CLEVIS.

SPECIFICATION forming part of Letters Eatent No. 701,540, dated June 3,1902.

Application filed March 15,1902. Serial No. 98,334. (No model.)

To all whom it may concern.-

Be it known that we, J AMES H. CHIDEsTER and WILLIAM TUBK, citizens ofthe United States, residing at Sibley, in the county of Osceola andState of Iowa, have invented certainnewandusefullmprovements inClevises; and we do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates to clevises for plows, cultivators, and the like;and its object is to provide a clevis capable of the smallest possibleadjustment, so that it will be applicable to any agricultural implementof the class mentioned, however great the variation in the width of thedraft-beam may be. Clevises have been proposed in which this adjustmentis made by a series of holes, alink, and a pin to fasten the link in oneof them; but it frequently happens that the degree of adjustment thusprovided is not fine enough, so that in the case of a plow-beam, forexample, to which the clevis cannot be exactly fitted, there is anamount of lateral play which interferes with the proper draft of theplow. By our invention this difficulty is avoided, since the adjustablelink is secured to the clevis by a sliding connection, so that it can beset at any point within the range of its movement.

In the accompanying drawings, Figure 1 is a top plan view of the end ofa plow-beam and a clevis embodying our invention. Fig. 2 is a sideelevation of the same.

The end of the plow-beam Ahas secured to it on each side a metallicplate B, forming jaws to receive the clevis C. The jaws are preferablywidened vertically at their front ends to provide for a series of holes5, those in one jaw standing opposite those in the other, so that bymeans of suitable fastening devices a clevis O can be attached theretoat different heights.

The clevis extends horizontally across in front of the jaws B, andconsists of a metallic bar having along its front edge a series oftransverse holes 0 for the adjustment of the draft ring or shackle D, towhich the draftchain E is hooked. These parts are not substantiallydifferent from those now in use.

.Ourinvention relates particularly to the means by which the clevis isfastend to the jaws. Near one end of the clevis is a rear-Wardly-extending lug 0, preferably integral with the body of the clevisand bifurcated to receive one of the jaws B. The rear edge of the clevisis provided with a rib c on both sides, preferably slightly undercut, asshown. A bifurcated block C is fitted to slide along this rear edge ofthe clevis and is provided with a flange or flanges c which engage withthe rib or ribs 0 and retain the block in place on the clevis. It can beslid along the clevis to any desired point to accommodate itself to anywidth between the j awsB, which are received between the ears 0 of thelug c and block G. The ears are perforated. transversely to permit afastening-pin F to be passed through them and the jaws. The pin has ahead f at one end and may be prevented from accidental removal by acotter-pin f passed through a hole in its other end.

It is evident that this clevis can be readily and quickly adjusted tobeams of different widths, as the sliding block gives aninfinitefineness of adjustment within the range of its movement.

Having described our invention, what we claim is- The combination withparallel jaws, of a clevis having means for the adjustable connection ofa draft-chain and provided with devices whereby it can be attached tojaws of any width, consisting of a stationary lug on the clevis toengage with one jaw, ribs along the rear edge of the clevis, and a blockadapted to engage with the other jaw and having flanges engaging withthe ribs on the clevis.

In testimony whereof we affix our signatures in presence of-twowitnesses.
